ZomBee Watch is a citizen science project that needs your help to learn if and where honey bees are being taken over by the zombie fly. This project is kind of gross but honey bees are so important that we thought it was worth it!

To do this project, you'll need to collect and observe a bee, following instructions found at

This project might take one day (if you don't find any bees) or up to 30 days if you do find a bee. That's typically how long it will take for a pesky zombie fly to spring to life from it's poor host the honey bee. In any case, review and print this form, then come back to when you are ready to enter all of your data and upload pictures.

Your sample's location

Based on the available information, this is your samples's point on the map. If this is not correct, you can drag the marker to the correct spot.

Did you collect any bees?

If you did not collect any bees, enter today's date, enter "0" for the "Number of bees collected," then scroll down and click "Submit data." You're done. Thank you!

If not, enter today's date and enter "0" for the "Number of bees collected.

Did you see any maggots or pupae?

Look for zombie fly maggots or pupae after 5-14 days. If the bees were infected, maggots should have escaped and some or all of them have changed into pupae. If you have found no maggots or pupae, enter "0."

Did you see any zombie flies?

Look for adult zombie flies after 14-30 days. If there were none, enter "0."
